Fatal heart condition symptoms and conditions

It's 3:00 in the morning and I am awake again convinced I must have heart failure. I've been on Lisinopril for several months and recently have experienced swelling of the tongue, throat, and face. I also have hair loss, shortness of breath, fatigue, and tingling in my arms. Until I found this site I had no clue as to the cause of these symptoms. Actually, afraid to go to the doctor for fear that I had some potentially fatal heart condition or worse. Now, however, I'm making an appointment tomorrow right after throwing those pills into the trash. I think I can sleep now. Thanks for input.
